top: tweak logic associated with keyboard translations
This commit most significant change is the elimination
of the kbd_ENTER entry from that tinfo_tab in iokey().
That entry was a useless artifact left from the commit
which is shown below. It makes no sense to 'translate'
a keystroke into something it already was (i.e. '\n').
The remaining changes just reorder those table entries
for a progression consistent with vim keys: h,j,k & l.
Reference(s):
. fix 'iokey()' flaw preventing proper translations
